Application July 13, 1937,-Serial No. 153,353 eolaims. (01. 229-6)- rected to that type of receptacle disclosed in my copending application Serial No. 63,623, filed February 12, 1936.

One of the objects of the present invention resides in the provision of a receptacle of the character indicated comprising a two-part container adated to house vacuum tubes such as radio tubes,

electric light bulbs and the like, with due provision for testing thetubes or bulbs without removing the sanie from the receptacle, so that the purchaser may be assured that the contents of the container or package are genuine so long as the container has not been ruptured or mutilated. "I

Another object of the present invention resides in the provision of receptacles of the character indicated of improved construction and assembly of the parts to attain the object above'referred to, as will be pointed out hereinafter'in detail in connection with the description of the accompanying drawings.

It is to be understood-that the'invention may be practiced in connection with containers for various types and sizes of vacuum tubes and electric light bulbs, and that the relative dimensions of the parts of the containers may be varied according to the specific types of tubes'or bulbs to be packaged.

; A further object of the present invention resides in the provision of a receptacle which can be opened 'for testing tubes with terminals or electrodes at both ends without removing the tube from the receptacle and wherein the receptacle must be mutilated in order to remove the tube thereby clearly indicating to the purchaser F that a spurious tube has been substituted for the genuine.

A still further object of the present invention is the provision of a convenient apparatus for assembling the parts of the receptacle as will be hereinafter more fully described.

} Referring to the drawings in detail and first of all to Fig. 1 which shows the blank from which the outer container is formed, the numeral .8 designates the front panel, 9 and ID the side panels, and H the rear panel, provided with a flap or extension l2 to beadhesively secured to v .the inside of panel 9 when-the receptacle is aslines l5, while the panels 8 and II have relatively i5. ably in arcuate form and extending substantially long fiapsor extensions l6 and I1 hinged or foldably secured thereto along creases or fold lines H3. The panels also are provided at their opposite ends with flaps or extensions l3, l6, I4

and I1 corresponding to the panels l3, I6, l4

and I1, respectively.

This blank from which the outer container is constructed is also provided with special means to form a cover for. one end thereof, such means consists in perforations or weakened lines l9 on the panels 9 and 10. Preferably the perforations or weakened lines l9 extend substantially half way across the panels 9 and Ill and are in alignment with the ends of an incision 29, which is made entirely across the panel 8, preferhalf way across the panels 9 and I and connecting with the weakened lines I9, as indicated at 25. The vertical creases or fold lines 22 between the panel 8 and the panels 9 and ID are provided with longitudinal slits 23 which extend slightly upwardly from the incision 20. The purpose, of these slits 23 will be pointed out hereinafter.

The blank of Fig. 1 is shown in assembled or closed position in Fig. 3, and it will be noted that when the upper portion of the container is broken along the lines l9 a cover C is provided to permit access to the interior, this cover being hinged to the panel II. that the weakened or perforated lines l9 may be provided to extend the entire width of the panels 8', 9 and ID, if desired, instead of having the incision 20, this construction being within the purview of my invention.

In Fig. 2 I have illustrated a preferred form of blank from which the inner wrapper, which supports the bulb or tube in the outer container, is formed, and wherein there are opposite end panels 24 and 25 connected by a side panel 26 along creases or fold lines 21 and 28. The end panel 25 is also connected to a longitudinal side panel 29 which is provided with side flaps or extensions 30 and 3| along opposite edges. The panel 26 has lateral extensions or side flaps 33 and 34 corresponding to the flaps or extensions 30 and 3| of panel 29. End flaps or extensions 35 and 36- are provided at opposite sides of the end panel 25 and disposed at right angles thereto when the wrapper is formed, as shown in Fig. 5. Thus, when the panels 26 and 29 are brought substantially into parallelism they will form opposite side walls of the inner wrapper and then the flaps 35 and 36 may be bent downwardly and flaps 30, 3|, 33 and 34 bent inwardly to form the other side walls of the container. The end panel 24 has a tab 32 adapted to be adhesively secured to the inner surface of the panel 29, .to provide a rectangular structure with the panels 24 and 25 at right angles to the panels 26 and 29, thus form ing two ends and side walls of the inner wrapper, with the other sides open to permit insertion of the bulb or tube as will be described presently.

It will be noted that the panel 25 is provided with an opening 38 through which the electrodes or prongs 39 of the tube or bulb project. The opening 38 may be of any desired shape and size to accommodate different types of tubes and bulbs/that is, the opening may be circular or noncircular. For the purpose of definitely loeating the electrodes or prongs 39 for ready application to the testing apparatus, I prefer, how

ever, to provide a substantially straight edge 49 along one side of the opening in definite relation to the panel 8 of the outer container. This prevents twisting or rotation of the bulb or tube Of course, it is to be understood within the inner wrapper. If desired I may also provide notches or slits at the point designated 4] at the ends of the edge 40 to serve as keepers 'for certain of the prongs of the bulb or tube and also to facilitate insertion of the bulb into the assembled irmer wrapper.

The end panel 24 has connected thereto or extending therefrom along opposite edges extensions or end flaps 42 and 42a. which are creased or provided with fold lines at 43. The extensions 42 and 42a are also preferably creased or provided with longitudinal fold lines at 44, which meet a central crease or fold line 45 in the panel 24 at opposite sides of the opening 46. The purpose of the transverse creases 44 and 45 is to permit partial folding of the panel or end wall 24, as will be described presently, to extend the length of the inner wrapper after the tab 32 has been secured to the panel 29, permitting the end 41 of the tube or bulb l to be inserted through the opening 46, as shown in Fig. 6, after the prongs or electrodes the panel 25. It will be appreciated from the foregoing that the inner wrapper is completely assembled, as shown in Fig. 5, before thetube is inserted. With the inner wrapper thus formed it is merely necessary in order to open the wrapp'er to open the fiaps 36, 30 and 34 outwardly, and apply pressure to the side walls 26 and 29, to cause-the lower end or panel 24 of the wrapper to fold outwardly along the fold lines or creases 44 and 45 to elongate the inner'wrapper whereby to facilitate insertion of the tube or bulb, after which the panel 24 may be straightened and the flaps folded back to their original-position, as illustrated in Fig. 5, to firmly support the tube or bulb between the panels 24 and 25.

The inner wrapper containing the tube or bulb may then be inserted in the outer container with the extensions on the flaps 42 and 42a projecting below the fold lines l5 and N3 of the outer container,-as illustrated in Fig. l. The flaps or extensions l3 and I4 of thejnner Wrapper are then folded inwardly and adhesive is applied to the exposed inner surfaces of the flaps l6 and I1 and the flaps 42 and 42a, as shown in Fig. 7, and the flaps l1 and 42a folded inwardly upon the flaps l3 and I4 and adhesively secured thereto, the flaps l6 and 42 are then folded in overlapping relation upon the flaps l1 and adhesively secured thereto.

This folding and sealing, as will be seen from Fig. 6 will securely hold the flap 42a of the inner wrapper between the flaps 13, I4 of the outer container and the flap I! of the outer container and the flap 42 of the inner wrapper between the flaps I6 and ll of the outer container in such a manner as to maintain the inner wrapper against relative movement with respect to the outer container and be securely held therein so that the same cannot be removedfrom the outer container without mutilation as will be appreciated.

The scoring or fold lines IS on the panels 9 and I 0 of the outer container which carry the flaps l3 and I4, it will be noted from Fig. 1, are out of alignment with the fold lines I 8 on the other panels to accommodate the folding and sealing operation just described.

The flaps l3, l4, l6 and 1'! at the other end of the container are also similarly provided withor electrodes 39 extend through the opening 39 of the panel of the inner wrapper 'in' proximity to the perforations l9 and slit 20. It will be'appreciated that the electrodes or prongs 39 will be exposed for testing when the receptacle is opened by breaking the walls 9 and I9 along the perforations or weakened lines I9 and by swinging the cover C on its hinge to open position. In this connection it will be noted that the cover C has been moved to a point below the electrodes and out of the way of the testing apparatus. As will also be seen from Fig. 4 the upper end of the inner wrapper projects beyond the weakened lines l9 and incision 29 to provide a shoulder for the cover C. The forward corners of the cover C, as

. above mentioned, are provided withslits 23 and the incision 29 isarcuate to form a lip. The purpose'of this arrangement is to facilitate closin -of the cover after, the same has been opened for testing of the tube. It will be appreciated that when the lip engages the shoulder the lip will be moved outwardly causing theslits 23 to open,

whereby the front wall of the cover C may pass readily over the shoulder into closed position.

It will also be noted that the preferred shape of the opening 38 which definitely locates the prongs or electrodes 39 in predetermined position greatly facilitates the application of the prongs or electrodes 39 to the sockets of the testing aparatus by providing a definite position of the carton.

when the test is made.

In Fig. 6 the tube is illustrated as having an end or teat 41, which in certain types of tubes must also be contacted when testing the tube,

whereas, in other types of tubes the application of the prongs or electrodes 39 alone to the testing apparatus is sufilcient.

In Figs. 8 to 13, inclusive, I have shown a modification of my invention which embodies the general object of preventing relative movement between the inner and outer parts of thereceptacle, and permitting testing of tubes having electrodes or terminals at both endswhile maintaining the tubes sealed withinthe receptacle.

In Fig. 8 the numerals l3, l9, l6, l4, II, II, i2, 29 and 23 designate the' same parts of the outer wrapper as in Fig. 1, and are located at the end of the container which is adapted to be broken open to expose the prongs 39 of the tube for testing. In other words, the construction at this end of the outer part of the receptacle is the same as in Fig. 1. I InFig. 9 the numerals 25, 26, 21, 29, 39, 3|, 32,

33, 34, 38 and 49 designate the same parts as in Fig. 2, and are foldable in the same manner as explained in connection with Fig. 2 to'permit the insertion of the prongs 39 through the opening 38;

The modification of the invention illustrated in Figs. 8 to 13 residesin the constructionof the parts of the inner and outer wrappers at.

the other end of the receptacle, which is the normally sealed end where the respective wrappers are secured together against relative sliding movement or removal.

Referring to. Fig. 8' wherein I have illustrated with parallel incisions 53 and parallel fold lines or creases 55 extending at right angles to the incisions 53 to form a rectangle or square. A

nections are provided which are to be subsequent- 1y ruptured .to expose one end of the tube for testing, as will be described presently.

In Fig. 9 the numeral 59 designates an end panel of the inner wrapper similar to the end panel 24 of Fig. 2, and is provided with flaps 69 and 64 corresponding tothe flaps 42 and 42a of Fig. 2. The flaps 59 and 64 have extensions 92 and 66 similar to the extensions on the flaps 42 and 42a of Fig. 2. The extensions 62 and 66, however, are shorter thanthe corresponding extensions of Fig. 1, the same being equal to the width ,of the strips 58 of the flaps 59 and 5| of Fig. 8, so that when these extensions are folded, as will be described presently, their edges will be spaced from each other instead of abutting each other, as is the case with the corresponding extensions of Fig.2. i

\ In order to assemble the parts shown in Fig.

8 and 9 to form a sealed receptacle with a tube enclosed therein, the blank of Fig. 9 is folded and the tab 32 secured to the panel 29, as in the case of the form illustrated in- Fig. 2. When foldedthe inner wrapper of Fig. 9 will assume the position shown in Fig. 10, which corresponds to the The inner wrapper containing the tube may then be inserted into the outer container by sliding it through the open end until the creases 6| and 61 are located properly relative to the creases which unite the flaps 59 and 5| to their respective panels, leaving the extensions 62 and 66 projecting from the outer container as shown in- Fig. 11. When theparts are in this position the upper end of the inner wrapper containing the tube projects beyond the weakened lines l9 to provide a shoulder'for the cover as shown and described in connection with Fig. 4. The upper end of the outer container of Fig. 8 may then be sealed by folding the flaps I3, l4 toward each other andthen the flaps I6 and I1 one over the other with an adhesive applied between the flaps l6, H in the same manner as described with respect to the form shown in Fig. 1.

In sealing the lower end of the receptacle of 'Figs. 8 to 13, inclusive, to unite the respective parts. against relative sliding movement and prevent removal of the tube from the receptacle without mutilating the receptacle, the inner sur-. faces-of the extensions 62 and 66 and the inner surfaces of the flaps 56 and 52 are first provided with adhesive, as illustrated in Fig. 11.

The flaps 59 and 5| are then folded inwardly, after which the extension 62 of flap 69 and extension 66 of flap 64 are folded toward each other and superimposed on and secured to the tabs 59 and 5|, as shown'in Fig. 12. It will be seen from this figure that a rectangular openingis provided of substantially the same dimensions as. the

rectangle formed by the incisions 53 and fold lines 55 of the flap 52. The flap 56 is then folded over'upon and secured to-fiaps 59 and 5|;

The flap 52 is then folded over upon the flap 56 and secured thereto. The folding may be done either by hand or by standard folding machinery. It will-be appreciated that when the folding is completed the extensions 62 and 66 of the inner wrapper are securely sealed and held between the flaps of the outer container as in the case of the receptacle of Figs. 1 to 7.

Inasmuch as the present embodiment of my invention is adapted for use in connection with receptacles containing tubes requiring testing at both ends, the other end of the receptacle may be opened along lines I9 and 20 in the same manner as explained in connection with my preferred form, so that the end of the tube where the electrodes 39 are located are exposed for application to testing apparatus. The terminal or electrode 63 may be exposed for testing by merely pressing on the end on both sides of the incision 56 to rupture the connections of this incision and press the flaps 54 and 54" thus formed inwardly whereby to expose the terminal 63 as shown in Fig. 13.

It will be appreciated that the construction and arrangement herein described, and particularly the method of adhesively securing the inner wrapper to the container by overlapping the tabs to secure the tabs of the inner wrapper securely between the tabs or flaps of the outer container is such as to positively prevent removal and substitution of tubes in an original container constructed in accordance with the invention without clear indication that the original container has been" broken, opened or partially destroyed.

If the test of the tube proves the same to be eflicient, the container is readily closed by swinging the cover C, formed by the upper portions of panels 8, 9 and I0, above the'slit 20, and perforations l9, upwardly from the position of Fig. 4 to the original position of Fig. 3. In this connection the slits 23 along the creases 22 facilitate the closing movement by giving flexibility to the cover when it is swung over the shoulder S of Fig. 4 provided by the flaps 35 and 36 of the inner wrapper and the wall 26 of the said wrapper, as hereinbefore explained.

In actual tests I have found the construction to be not only simple in method of assembly of the parts, but to also be rigid in nature providing the desired protection to the contents while also affording a guarantee of integrity of the merchandise.

The method of assembling is facilitated greatly by the form shown in Figs. 14 to 17', inclusive, comprising a box-like structure which may be made of any suitable material such as wood, metal or fibre board, and comprising walls 16, certain of which may be provided with longitudinal slots II to permit the fingers of the operator to contact a carton as it is inserted in the form. The provision of the slots H is an optional feature, as obviously the cartons may be inserted in the form if all of the walls of the form are solid. v

Within the form and between the opposite Walls 10 is block 12 which may be made as an integral part of the form, or which may obviously be a, separate part, so arranged and proportioned relative to the walls 10 as to provide spaces 13 to receive portions of the sides of the outer part of the carton when inserted. The block "12 is further so proportioned in length relative to the walls 10, and the particular cartons to be received in the form for assembling as to terminate at a predetermined point between the top and bottom of the form to constitute an abutment 14. The block 12 is also provided with a chamber 15 which receives the electrodes of the to the insertion of the outer wrapper or carton,

because one operator may attend to' the insertion of the bulbs in the inner wrapper, and an-' other may attend to the insertion of the outer wrapper in the assembling forms, or one person may perform the entire operation. In either event, it is essential that the outer wrapper or carton be inserted in the form with the flaps [6, ll contacting the lower ends of the grooves or slots 13, as shown best in Fig. 16.

As previously mentioned the relative propor-' tions of the forms and the cartonstobe assembled thereon is predetermined. This is clearly illustrated in Figs. 15 and 16 where the parts of the carton are inserted in the form with end flaps, corresponding to similar flaps ofthe embodiment of the invention shown in Fig. 11, disposed above the top of the form. The exact or approximate relative folding position of the flaps of the inner and outer wrappers, which secure the two parts together against relative sliding movement is determined by the block 12, as shown in Fig. 16, which illustrates the end 25 of the inner wrapper abutting the top of the block 12, and the electrodes of the tube extending into the chamber 15. When this position is reached upon the insertion of the wrapper of Fig. 5 with a tube inserted therein, into the outer wrapper and form of Fig. 14, the end flaps of the inner and .outer wrappers are in position to be folded along their creases into superimposed relation to be adhesively secured together as shown in Fig. 6, from the position of Figs. 7, 11 or 15. 1

lifter the container is removed from the form with the tubeor bulb contained therein, it is only necessary to fold the flaps at the other end of the outer wrapper into superimposed relation and secure them together in the manner hereinbefore described. a If desired the open end of the forms in which the blanks are assembled may be made substantially funnel shape to facilitate insertion of the This is illustrated in blanks within the forms. Fig. 14, where extensions 16 are provided on the upper ends of the walls of the form and incline upwardly and outwardly. Thus, the flaps l3, I4, l6 and I1, if not in exact alignment with the walls 8 and 9 of the carton will be guided into the form by contact with the inclined extensions 16. Obviously, if desired, and where a form made of cardboard or fibre board is used the extensions 16 may be in the form of tabs or flaps individually connected to the walls of the form along creases to provide a flexible connection between the main part of the form and the tabs-which provide the funnel-likeend. In such cases the tabs would be separate at the several corners of the form. In either event and in either construction the provision of the funnel-shaped end on the form is optional, and a form made with a plain open 76 and as shown in Figs. 15 and 16 may be provided.

It isto be understood that various changes and modiiications may be made in the structures herein illustrated and described without departing from the spirit and scope of my invention.
